Shaft alignment regulation and measurement device

Abstract

The present invention discloses a shaft alignment regulation and measurement device. The device comprises a first shaft to be measured, a laser emission device, a first connection flange, a second shaft to be measured, a laser receiving device, a second connection flange, a shaft alignment measurement support and an infrared ray measurement clamping block; the laser emission device and the laser receiving device are respectively fixed on the first shaft to be measured and the second shaft to be measured; the first connection flange and the second connection flange are respectively located at connection ends of the first shaft to be measured and the second shaft to be measured; the shaft alignment measurement support is fixedly connected with the laser emission device; and the infrared raymeasurement clamping block is absorbed at the bottom portions of the first shaft to be measured and the second shaft to be measured. The shaft alignment regulation and measurement device is taken as alaser measurement device for alignment errors based on the CCD sensing technology, is mainly applied to detection and regulation of alignment errors of two coupling drive shafts of the rotary machinery in the installation, debugging and maintenance processes and ensures that the axes of the drive shafts are located in the same line so as to meet the requirement of high-precision installation.

Description

technical field [0001] The invention relates to the technical field of shaft alignment detection, and more specifically relates to a shaft alignment adjustment measuring device. Background technique [0002] With the rapid development of modern industry, the safe, reliable and continuous operation of rotating machinery is very important. Once a fault occurs and the shutdown occurs, it will cause huge economic losses and may also have serious social impacts. Among all kinds of common faults of rotating machinery, the misalignment fault of the rotor system is one of the most frequent faults, accounting for about 60% of the total faults. Because the operation of the rotor in the state of misalignment will cause the deflection of the shaft, mechanical vibration and wear of the bearing, etc., it is quite harmful to the stable operation of the system. Therefore, the alignment error between the rotors has always been the focus of engineers and designers. extensive attention. The ...

Problems solved by technology

[0003] At present, in China, few scholars have conducted in-depth research on the measurement of centering error. In my country, most of them use feeler gauges, dial gauges and other testing methods to complete the measurement. Obviously, the accuracy is not high.

In recent years, some enterprises have introduced imported laser alignment instruments. In the actual operation process, it is necessary to manually rotate the measuring instrument to different angles for measurement, and the measuring instrument must be reset to zero for alignment many times during the alignment process. The operation is cumbersome and takes a long time, not only the operation is complicated, but also the price is expensive and it is not suitable for popularization
